Running an Oppo 205 directly into amplifiers can be a great set up....in the right system.
The JC 1's might not qualify with their pretty sensitive (especially for ss) input of 1 V for full output, rather than the 2 V more commonly seen. This will reqiuire pushing back the volume on the Oppo 205 quite a bit, to be the point where range of volume control will be reduced, and perhaps more importantly resolution could be compromised.
